In a sand production line, especially in a wet sand production line, sand washing is essential to enhance the quality of the finished sand, making a sand washing machine indispensable.
The sand washing machine effectively removes soil and impurities from the sand surface while breaking the water vapor layer, aiding in efficient dehydration, sand washing, and cleaning, thus improving sand quality.
Various types of sand washing machines exist, each with unique characteristics and applications. How do you select the right sand washing machine? This article offers a detailed guide.
Common types of sand washing machines include spiral sand washing machines and impeller sand washing machines.
This type stirs sand and gravel using a spiral device in the equipment, mixing with water. The sand and gravel are gradually screened and discharged through the spiral action, achieving cleaning and screening. There are two variants: single-spiral and double-spiral sand washers.
It suits washing, grading, and impurity removal across metallurgy, building materials, hydropower, and is particularly good for construction and road construction sand.
Also known as a wheel bucket sand washing machine, this type moves sand and gravel in a wheel bucket, causing them to grind against each other to remove surface impurities. Strong water flow within the machine washes away impurities. The clean sand and gravel are then carried by blades into a discharge tank, achieving thorough cleaning. Variants include single, double, and triple-row wheel buckets.
This machine often integrates with a sand making machine to create high-quality sand production lines used across transportation, chemical industry, mining, water conservancy, and hydropower fields.
The wheel bucket sand washing machine has a simple structure with fewer wearing parts and occupies a small area post-installation. To prevent bearing damage from water, sand, and pollutants, it isolates the impeller drive bearing from water and sand, reducing failure rates.
The spiral sand washer, with its slender and horizontal structure, is simpler but less convenient in installation compared to the wheel sand washer.
Wheel bucket sand washers typically clean materials around 5mm, whereas spiral sand washers handle both large and small materials efficiently.
Wheel bucket sand washers consume less water and minimize the loss of fine sand and stone powder, ensuring the washed sand meets standard requirements. In contrast, spiral sand washers experience more sand and gravel loss during washing.
The sand and gravel in a spiral sand washing machine undergo thorough cleaning, resulting in higher quality finished sand.
The spiral sand washing machine offers strong cleaning capacity for sand with significant mud impurities, ideal for extensive sand production lines. Conversely, the wheel sand washer's capacity is smaller, fitting small to medium-sized production lines.
The wheel bucket sand washing machine uses less water, with minimal fine sand loss. The spiral sand washing machine, however, has higher water consumption and more gravel loss.
The wheel bucket sand washer is economical and efficient, suitable for projects requiring small output. For large-capacity needs, considering transportation costs, a spiral sand washer may be more appropriate.
Choosing the right machine involves several considerations:
Determine whether to use a spiral or impeller sand washer based on production requirements. The spiral type offers efficiency and high capacity but consumes more water and loses more fine sand. The impeller type has lower output but conserves water and fine sand, and is more budget-friendly.
Research manufacturers online and offline, visit their facilities, and evaluate their strength and production processes to ensure you purchase a high-quality machine.
Get quotes from various manufacturers to find the most cost-effective option. However, avoid choosing solely based on low prices to avoid lower quality and higher maintenance costs.
Ensure the manufacturer offers excellent after-sales service, timely replacement of parts, and quick repair services to maintain optimal equipment operation and minimize downtime.
Choose manufacturers with positive feedback from the majority of their customers, avoiding those with numerous negative reviews to prevent potential economic losses.
Different sand types require different configurations:
If using natural sand like river or sea sand, configure your production line accordingly, considering various factors for optimal setup.
Producing artificial sand requires more than a sand washing machine; additional sand-making equipment is necessary. Raw materials like river pebbles, limestone, granite, or basalt determine specific production line configurations.
If the sand is fine, include a fine sand recovery machine. Otherwise, fine sand loss during washing can reduce finished product quantity and quality, affecting sand gradation and causing environmental issues. A fine sand recycling machine after the sand washer can mitigate these losses and optimize sand and gravel resource utilization.
